Stainless steel insulation cup is divided into: ordinary insulation cup (the boiling time after the boiling water is poured in is generally less than three hours), vacuum insulation cup (through the vacuum process, can make the boiling water insulation more than 8 hours)

Vacuum insulation cup, the length of the insulation time depends on the structure of the cup body and the thickness of the cup material.

In general, the thinner the cup material, the longer the holding time. However, the cup body is easy to damage and deform, affecting the service life; the outer layer of the vacuum cup liner metal film and copper plating and other measures can also increase the degree of insulation; large capacity, small diameter vacuum cup holding time is longer, the contrary small capacity Large-diameter vacuum insulation cup has a shorter holding time; the service life of vacuum cups also depends on the cleaning and vacuuming time of the inner layer of the cup. The most important is the structure of the vacuum furnace.

The vacuum equipment used in the society for vacuum suction cups has vacuum exhaust stations and vacuum brazing furnaces. There are about two types of vacuum equipment. One type is tail vacuum exhaust table; the other brazing furnace type. Brazing furnace is divided into: single room, multi-room, pumping speed multi-room.

Single furnace integrated vacuum brazing furnace. The evacuation cycle time of the furnace is long. If the manufacturer wants to improve the production efficiency and shorten the evacuation time, it will affect the service life of the cup. The service life of the cup is only about 8 years. A vacuum cup venting table and advantages: a vacuum cup produced by a vacuum exhaust table with a tail exhaust. When the vacuum is used, the heating temperature is about 500°C. The shell of the vacuum cup is not easily deformed, but the copper tube welding place is easily touched. Leakage, special protection in the processing of semi-finished products.

In addition, a large class is a vacuum brazing furnace, which can be divided into three types. Unexpectedly, the vacuum insulation cups that we usually use are no different from the general insulation cups in terms of appearance, and the vacuum insulation cups are used in the production process. General insulation cups are much more complex and technically more difficult. Therefore, vacuum insulated cups are at least twice as expensive as regular insulated cups.
